What is TSS and why is it a concern?
Toxic Shock Syndrome (TSS) is a rare but serious bacterial infection linked historically to the prolonged use of tampons. The condition is caused by toxins from Staphylococcus aureus or Streptococcus pyogenes bacteria. TSS symptoms can escalate quickly, making awareness and proper hygiene essential for anyone using internal period products.
With the growing popularity of reusable menstrual discs, including award-winning brands like my mimi, many Australians are asking if discs carry the same risk as tampons.
Do menstrual discs increase the risk of TSS?
The short answer is that menstrual discs have a far lower risk profile compared to tampons, largely because they do not absorb blood. Tampons create a fibrous environment where bacteria can multiply. A disc, on the other hand, collects menstrual fluid without altering the natural vaginal environment or causing micro-tears.
While no product can be considered completely risk-free, there is currently no evidence to suggest that menstrual discs are a common cause of TSS. Cases linked to menstrual discs are extremely rare, and proper cleaning and usage practices significantly reduce any risk.
What is a menstrual disc?
A menstrual disc is a reusable or disposable device designed to collect menstrual fluid high in the vaginal canal, below the cervix. Unlike a cup, a disc doesn’t rely on suction to stay in place, which can make it more comfortable for many users.
The my mimi reusable menstrual disc is made from soft, medical-grade silicone and has been recognised for its safety and design, winning the “Best Sustainable Period Care Solution in Australia 2025”. With a flexible rim and a loop tab for easy removal, my mimi is designed to support effortless wear for up to 12 hours, even on heavy flow days.
How to reduce the risk of TSS with a menstrual disc
Like any internal product, proper hygiene is essential. Here are some steps to keep your experience safe and comfortable:
- Clean your disc thoroughly: Wash your reusable menstrual disc with warm water and a mild, fragrance-free cleanser after each use. Sterilise the disc between cycles by boiling it for 3–5 minutes.
- Avoid exceeding recommended wear times: my mimi can be worn for up to 12 hours, but it’s best to empty and rinse the disc twice a day. This maintains hygiene and ensures comfort.
- Check your hands before insertion or removal: Always wash your hands with soap and water before handling your disc to avoid introducing bacteria.
Menstrual disc vs tampon: TSS risk comparison
Tampons have been more commonly associated with TSS due to their absorbent materials and prolonged contact with the vaginal wall. A reusable menstrual disc like my mimi collects rather than absorbs, reducing the likelihood of bacterial growth.
Additionally, discs are smooth and soft, minimising irritation to the vaginal walls, which can sometimes occur with tampons and increase infection risk.
Why my mimi stands out
my mimi is trusted by thousands of Australians for its comfort, sustainability, and safety. Here’s why:
- Available in two sizes for a better fit:

When to see a doctor
If you experience symptoms like a sudden high fever, vomiting, dizziness, or a rash resembling sunburn while using any period product, remove it immediately and seek medical attention. While TSS is extremely rare, early treatment is critical.

Menstrual discs like my mimi are designed for safety, comfort, and sustainability. With proper hygiene and usage, the risk of TSS is extremely low. For those looking to switch to a reusable menstrual disc, my mimi offers an eco-friendly, affordable, and reliable choice.
